Application fll ed July 24, 1922. Serial No. 576,911. 7

To all whom 'it may concern:

.' Be it known that I,-WALTER -DAnor RYAN, a citizen of the UnitedStates, residing at Schenectady, in the county of Schenectady and Stateof New York, have invented a new and useful Improvement in Headlights,of -which the following is a specification. 4 My invention relates toheadlights and i 10 has for .its object to provide new and improvedmeans for fusing from a single light source the rays to light theroadway far in advance of the vehicle 'to which it is attached, and alsothe closely immediate surroundingsc A further'object is to provide meansto redirect downwardl' and outwardly' a certain portion of. the ightrayswhich would otherwise escape outwardly and upwardly from the source, soit can be utilized to illuminate an area close to the vehicle.

By reference to the accompanying draw ing and reading of the followingdescription a person skilled in the'art will readily understand theconstruction by which' I accomplish the desired objects. Flg. 1 is across sectional *Fig. 2 is a front View. 7 a I In the drawing thereference numeral 10 indicates the headlight housing,11 the reflector,12 thelamp and 13- removable glass containing casingfront. ,The lamp 12is mounted on an elongated shaft support 14 side elevation.

which causes it tojbe positioned in advance I of the housing, and theglass front 15 is provided with a protruding center portion 16 intowhich the lamp projects, asshown. The protruding portion 16 ispreferably constructed with prisms on its upper half L to project themajor portion of the light rays received thereon downwardly andoutwardly.

I By this construction the light rays from the lamp which impinge on thereflector 11 are directed forwardly through the glass front, in a longbeam to light the roadway far in advance of the machine, and therayswhich come direct from the lamp through the glass front (except thoseimpinging upon the upper part of the protruding portion 16) illuminatethe immediate surrounding to the lamp mounting, while a large portion ofthose rays that strike the upper part of the protruding portion 16 areredirected downwardly and outwardly immediately in front of the vehicle.The upper part of the protruding portion may, if desired, besand-blasted, or provided with any diffusing means'in preference to theprisms 16.

The protruding portion into which the lamp projects may be formed bymolding 'its central portion protruding outwardly from the planeo'fftheouter surface; the 75 positioning of the light source being suchthat it extends into the protruding portion of the lens, the uppersurface of said protruding portion being provided with refracting meansto redirectlight rays impinging thereon, outwardly and downwardly.

In testimony whereof I have signed the foregoing specification.

WALTER DARCY RYAN.
